Thirteen-year-old twins Vick and Tara have built an incredible machine--a loyal robotic watchdog named Daisy. But, when local crime boss Ms. Alba schemes to add Daisy to her robot army, Vick and Tara must go to great lengths to protect their prized pet. Because Daisy is more than just any robot--she's their constant protector, and together the three make a great team.

Vick and Tara are determined to stop the mob from tearing their little family apart. And they might just succeed! Sure, the evil Ms. Alba has more robot watchdogs, but none are as smart--or as faithful--as their Daisy. Plus, if things get too dangerous, Tara could always upgrade their pet. With her mechanical skills, she could make Daisy bigger, stronger, and a lot more intimidating! 

Deep within the enchanted woods in the town of Watch Hollow stands the once-grand Blackford House, whose halls hold a magical secret: a giant cuckoo clock that does much more than tell time. But when the clock’s gears cease to turn, an evil presence lurking among the trees begins to come out of the shadows.

When Lucy and Oliver Tinker arrive in Watch Hollow, they have no idea that anything is wrong. A mysterious stranger has made their father an offer that’s too good for him to refuse. All Mr. Tinker needs to do is fix the clock at Blackford House and fistfuls of gold coins are his to keep.

It doesn’t take long, however, for the children to realize that there is more to Blackford House than meets the eye. And before they can entirely understand the strange world they’ve stumbled into, Lucy and Oliver must join forces with a host of magical clock animals to defeat the Garr—a vicious monster that not only wants Blackford House for itself, but also seeks to destroy everything the Tinkers hold dear.

Vivien Thomas's greatest dream was to attend college to study medicine. But after the stock market crashed in 1929, Vivien lost all his savings. Then he heard about a job opening at the Vanderbilt University medical school under the supervision of Dr. Alfred Blalock. Vivien knew that the all-white school would never admit him as a student, but he hoped working there meant he was getting closer to his dream. 

As Dr. Blalock's research assistant, Vivien learned surgical techniques. In 1943, Vivien was asked to help Dr. Helen Taussig find a cure for children with a specific heart defect. After months of experimenting, Vivien developed a procedure that was used for the first successful open-heart surgery on a child. Afterward, Dr. Blalock and Dr. Taussig announced their innovative new surgical technique, the Blalock-Taussig shunt. Vivien's name did not appear in the report.

Overcoming racism and resistance from his colleagues, Vivien ushered in a new era of medicine children's heart surgery. Tiny Stitches is the compelling story of this incredible pioneer in medicine.

 For nearly a century, Victorian London relied on "climbing boys"--orphans owned by chimney sweeps--to clean flues and protect homes from fire. The work was hard, thankless and brutally dangerous. Eleven-year-old Nan Sparrow is quite possibly the best climber who ever lived--and a girl. With her wits and will, she's managed to beat the deadly odds time and time again.

But when Nan gets stuck in a deadly chimney fire, she fears her time has come. Instead, she wakes to find herself in an abandoned attic. And she is not alone. Huddled in the corner is a mysterious creature--a golem--made from ash and coal. This is the creature that saved her from the fire.

Sweep is the story of a girl and her monster. Together, these two outcasts carve out a life together--saving one another in the process.

When a group of US Marines fighting in the Korean War found a bedraggled mare, they wondered if she could be trained to as a packhorse. They had no idea that the skinny, underfed horse had one of the biggest and bravest hearts they’d ever known. And one of the biggest appetites!

Soon Reckless showed herself more than willing to carry ammunition too heavy for the soldiers to haul. As cannons thundered and shells flew through the air, she marched into battle—again and again—becoming the only animal ever to officially hold military rank—becoming Sgt. Reckless—and receive two Purple Hearts.

On a cold January day in 2017, nearly two months before her due date, Nile hippopotamus Bibi gave her keepers at the Cincinnati Zoo & Botanical Garden a big (little) surprise - a tiny newborn hippo, no bigger than a football.  The first premature hippo born and raised in captivity, baby Fiona was an underdog from the start:  she couldn't nurse, she couldn't stay hydrated, and she wasn't thriving. But the staff at the zoo knew they could save her.  It would take creative thinking and teamwork. They would have to study the makeup of hippo milk for the first time ever and reach out to medical colleagues, including a team at the local Children's Hospital with superior vein-finding skills,  to ensure that Fiona would begin to gain weight and become healthy. When Fiona began to thrive, her star began to rise, and soon she became an internet sensation, her picture and videos garnering thousands and thousands of likes and fans on Instagram and Facebook.  Now a Fiona appearance at the Zoo mimics a Beatles concert.  What made this little, now big, hippo such a big hit with people all over the world?  And what's in store for her and her family in the future?

Chase's memory just went out the window.

He knows he's Chase. But who is Chase? When he gets back to school, he sees that different kids have very different reactions to his return. 

Some kids treat him like a hero. Some kids are clearly afraid of him.

Pretty soon, it's not only a question of who Chase is--it's a question of who he was . . . and who he's going to be.
